(First, can anyone get me the file with the USA rom that is not a .rar file, because most files that i am finding are rars)
How do you make loops (upside down parts) on any roller coaster? And why do you think that you can't cross over another section of the roller coaster, like another part of the track going over another one below? Help!!!!!!!

you get the loop for the roller coaster when you have done a few of the countires it's like a gift for getting so far through the game. i wondered why i couldn't get this with the roller coaster. don't ask which country you get it with because i can't remember.
